The core message: Good seed is the primary factor in raising the efficiency of raising pigs. The quality of breeding pigs is the key link in the success or failure of raising pigs. Farmers raising pigs on a small scale (especially those who have just entered the pig-raising industry) often introduce pigs. Most farmers prefer large-scale pigs, and pigs with large numbers of pigs are more suitable. In fact, this will bring hidden dangers to future production. In the introduction process should pay attention to the following aspects:
I. Two preparations should be made before the farm is introduced
1, according to the actual situation to develop a scientific and reasonable introduction program, and do a good job before the introduction of various preparatory work.
2. Survey and selection of target breeding farms
1) Select a breeding farm with a moderate scale, a high degree of trust, and a high level of technical services;
2) When selecting a farmer, the health status of breeding pigs should be put first;
3) The pedigree of the breeder should be clear;
4) Choose a better home after-sales service;
5) Try to buy from a farm, otherwise it will increase the possibility of illness;
6) Selecting a field home should be followed by indirect understanding or consultation, and then to the field and sales staff to understand the situation.
Second, to select the breeding pigs in the target field
1, production performance off:
Kind of boar: the requirements are pure, lively and happy, normal testis development, and not much effusion of the foreskin;
Sows: In order to purchase sows, we must select individual sows that are well-growth, have no morbid signs, respond to sensitive sows, have good genital development, and have large pupa and sagging cats with multiple nipples.
2. Diseases and diseases:
Pigs require health, no clinical signs and genetic disorders.
3, environmental adaptation:
When introducing, comprehensive consideration should be given to the difference between this field and the seed supply field in the regional environment and the pig farm microenvironment, and the consistency of the environment of the farm with the seed supply field should be achieved as much as possible.
III. Breeding of pigs and group five attention
1. Pay attention to segregation first: Newly introduced breeding pigs should be kept in the isolation house first, but not directly into the breeding pig production area.
2. Pay attention to disinfection and grouping: After the breeding pig arrives at the destination, immediately sterilize the ground around the dumping platform, vehicle, pig body and unloading vehicle, and then remove the breeding pigs, and feed them in groups according to size and male and female;
3, pay attention to strengthen management: first give the breeding pigs drinking water, rest 6 to 12 hours before feeding a small amount of feed, the second day can gradually increase the amount of feeding, 5 days before returning to the normal amount of feeding;
4. Observe the isolation and observation: After the breeding pig arrives at the farm, it must be kept in a separate house for 30 to 45 days and strict quarantine;
5, pay attention to exercise: after the weight of 90 kg of pigs, to ensure that each pig per day 2 hours of free exercise time, improve their physical fitness and promote estrus.
IV. Prevention of Seven Diseases Introduced in Spring Farms
The most common are swine fever, piglet paratyphoid, panting, Japanese encephalitis, infectious gastroenteritis, yellow and white piglets, blue ear disease. Before and after the spring will enter the peak period of swine fever, pig farmers should be as soon as possible injection of swine fever vaccine. In order to prevent yellow and white piglets, sows should be injected with E. coli 20 days before delivery. In addition to on-time injection of various vaccines to prevent swine diseases, another important measure is to do a good job in housing hygiene and strengthen feeding management.
Medical surgical masks are used to wear on the nose and mouth of medical staff in the operating room to prevent the spread of dander and respiratory microorganisms to open surgical wounds, and to prevent the spread of surgical patients' body fluids to medical staff, playing a two-way biological protection role. Medical protective masks fully meet the requirements of epidemic prevention and are one of the best and most effective materials for epidemic prevention at present.
Wearing masks correctly is an effective means to block the transmission of respiratory secretions. Choosing medical surgical masks can well prevent the spread of respiratory infectious diseases. How to wear it as follows:
(1) Wash your hands before wearing the mask, and avoid touching the inner side of the mask with your hands during the process of wearing the mask to reduce the possibility of the mask being contaminated;
(2) When wearing, distinguish the inside and outside, up and down of the mask, the light-colored side is inside, the dark-colored side is outside, one end of the metal strip (nose clip) is above the mask, and the folded surface is fully unfolded;
(3) Turn the side with the nose clip upwards, cover the mouth, nose and jaw, adjust the lower end of the mask to the proper position of the lower jaw, hang the elastic bands on both sides on both ears or tie the straps at both ends to the back of the head , then squeeze the nose clip so that the mask fits the face completely.
